Refoam question

Nice to know that yours looked just as bad - and came out so sweet!

Voice coil seems to travel OK and spider looks fine too.
Here in DK a re-cone job is about € 200-250,- per speaker, so it'll be the DIY-re-edge way first.

Btw: One of the LE5-8s need a re-cone-job - the structure of the cone is "soft" in one side. Might be better to get another (used) LE5, but I'm not certain of the different versions (LE5-2, LE5-8, LE5-12 etc.).
Does a scheme or list exist?

Yup - Zilch posted the link to the LE5 Matrix already.

Compare with system components in the L166 Horizon tech sheet, below.

LE5-8 is the original. LE5-12's were recommended as exact acoustic and visual substitutes (and show up on ebay frequently, because this type was used in several speakers). Anyway, I'd wait for nice LE5-8's.

Much more difficult (and costly) to replace would be the 066's, pretty rare since no longer servicable from JBL nowadays. Hope yours survived both undamaged also.

Actually I found a "spare" set of L166 for very little money (w. one LE5-8 needing repair though, both woofers in need of refoaming and a wood-job needed also...) so I have 3 working 066-units.
I'll look for one more in order to reconstruct all four L166s.
Or I'll sell the second set as spare parts (but not in the near future).


Again - Thx for help!

Sorry to have missed this.

Anyone interested and/or so remote as to needing to try this themselves can get the kits from Rick and follow this Resurround Step-by-Step thread...

It's been suggested to me, that if one has never refoamed a pair of speakers, they should not break their cherry on an LE14. Any comment?

[John]

Funny you should say that!!! The LE14A's were the first pair I did and they turned out great.

[Thom]

Is there anything special about them? What I was told was that Le14, Le10, and Le8 were all trickier because of the ring that goes around the outside of the surround.

Hello Thom

The square frame drivers have almost no wiggle room on the frame for the outer edge of the compliance. You drop the surround in and it's damn near an exact fit. With the round drivers you have quite a bit more space to move the outside edge of the surround around. You need to get the surrounds well centered on the cone and go from there. I found them a bit more challenging than the rounds. What I do is fit them dry to get an idea of how well centered the coil is and to see how well the inside edge lays out on the back side of the cone. One thing for sure is get the backside of the cone as clean as you can.

Or, front side on LE14As....

Yes Thats just the way it worked for me. Also the smaller the cone the easy'r they are to do.
